Mishimoto Silicone Post MAF Intake Hose Kit Blue IS300

The Mishimoto Silicone Post MAF Intake Hose Kit Blue IS300 replaces the factory air intake hose on 2001–2005 Lexus IS300 I6 3.0L vehicles to eliminate air leaks and restore consistent engine breathing for improved reliability and throttle response.

This silicone replacement addresses the common failure mode of the original rubber hose, which can become worn, cracked, or damaged over time and introduce unmetered air into the intake tract. By restoring a sealed airway at the post‑MAF location, the kit helps maintain accurate mass airflow readings and steady engine performance under normal and elevated load conditions.

Why this matters

• Restores intake integrity — Prevents vacuum and boost leaks that can cause drivability issues and degraded engine efficiency.
• Durable silicone construction — Resists aging and environmental degradation better than OEM rubber to maintain a reliable seal over time.
• Direct replacement fit — Designed for straightforward installation on 2001–2005 IS300 models to minimize installation time and maintain factory routing.

Installation and service notes

The kit installs at the post‑MAF location of the intake tract and is intended specifically for the 2001–2005 Lexus IS300 I6 3.0L application. Installation uses the factory clamps or supplied hardware where applicable to ensure a secure, leak‑free connection. Routine inspection of clamps and hose condition is recommended as part of scheduled maintenance.
